Return & Refund Policy
1. Return & Refund Eligibility & Validity Period We provide a 30-day after-sales service period for all original MCU chips and drone electronic components, valid only for factory quality defects, dead-on-arrival (DOA), wrong item shipment, and quantity errors. Returns and refunds caused by personal reasons are not accepted. All returned products must be brand-new, unused, with complete original packaging, labels, and accessories without any damage, modification or test traces to be eligible for after-sales application.
2. Non-Returnable & Non-Refundable Situations To avoid unnecessary losses caused by invalid returns, the following situations are not supported for return, refund or exchange: products with artificial damage, soldering disassembly, private modification, firmware flashing and secondary testing; products with normal appearance and no factory defects but returned due topersonal model mismatch, project adjustment, purchase error, unnecessary stock or personal usage concerns; products beyond the after-sales period; customized and special-spec components; bulk orders returned without valid quality reasons.
3. Cost Bearing Rules (Strict & Standard) For any return or refund application, customers shall bear all round-trip freight, customs clearance fees and related handling costs by themselves. The initial shipping fee of the original order is non-refundable in all cases.
4. Formal Refund Processing Rules After receiving and strictly inspecting the returned goods to confirm valid quality problems, we will complete the refund review and fund transfer within 3–7 working days. If the returned goods are inspected as no quality defect, artificial damage or invalid return, we will reject the refund application and send the goods back at the customer’s expense.
5. Exchange Service Regulations Exchange service is only available for orders with confirmed factory quality defects. For personal reasons such as model selection errors and project scheme adjustments, we do not support free exchange. Any voluntary exchange application by customers needs to be negotiated separately, and all resulting costs shall be borne by the customer.
